PROPERTIES OF SILVER. 



Silver has been known from the earliest ages, coin of that metal has been found dating 
back to 800 B. C, and in the Pyramids of Egypt linen stained black by salts of silver has 
been discovered. 

The Alchemists called it Luna or Diana, and we still call the fused Nitrate of Silver 
Lunar Caustic. The Latin name for it was Argentum from which we derive the term 
Argentiferous and the chemical symbol Ag. 

Silver is very ductile and the best conductor of heat of all the metals; its atomic weight 
is 108, its specific gravity varies from 10.43 t0 I 0-56, as it maybe cast, hammered, drawn, 
etc. It fuses at about 1832 F. (which is lower than the melting point of Gold or of Cop- 
per) and can be distilled at the heat of the Oxyhydrogen flame; in melting, it absorbs 
Oxygen from the air, which it gives off again on cooling, causing the molten mass to 
spurt when suddenly cooled. (Only pure silver acts thus) . 

Pure Silver may be obtained crystallized in Cubes and Octahedrons. It dissolves in 
Nitric Acid of medium concentration; concentrated Sulphuric Acid changes it into Sulphate 
of Silver at a boiling heat, while Muriatic Acid does not act upon it. Quicksilver unites 
with it, forming an Amalgam, and it is easily alloyed with many other metals by fusion. 

The characteristic test for Silver in (acid) Solution is made by adding Muriatic Acid 
or a soluble Chloride, when a white, curdy precipitate of Chloride of Silver is formed, 
insoluble in water or in acids, but soluble in Ammonia (also in Cyanide of Potassium or 
Hyposulphite of Soda); from the ammoniacal solution acids reprecipitate the Chloride of 
Silver. Very dilute solutions of Silver are rendered opalescent by applying this test. 



All compounds of Silver yield metallic Silver when fused with Carbonate of Soda 
before the blowpipe. 

Caustic Soda or Potassa precipitates Silver from its solution as greyish-brown oxide 
of S. insoluble in an excess of the precipitant, soluble in Nitric or Sulphuric Acid. 

Ammonia produces the same precipitate soluble in an excess of the precipitant and in 
Nitric or Sulphuric Acid. 

Carbonated Alkalies produce a precipitate of yellowish-white Carbonate of Silver 
soluble in Carbonate of Ammonia and in Nitric or Sulphuric Acid. 

Sulphureted Hydrogen and Sulphide of Ammonium produce a black precipitate of 
Sulphide of Silver which is decomposed by boiling Nitric Acid with elimination of Sulphur. 

Copper, Zinc and other easily oxidizable metals precipitate metallic Silver as a gray, 
spongy powder, and some organic substances act in a similar manner. 

Silver is found in its native state, alloyed with Gold, and as Sulphide of Silver, fre- 
quently with Copper Glance, Galena and other metallic Sulphides, less frequently as 
Chloride of Silver (Horn Silver) and rarely as Iodide or Bromide of Silver. 

The water of the oceans contains Silver in small proportions. 



We are indebted to Messrs. Falkenau & Reese, Assayers, for the above article. J. C. 






Note to Silver Table. 



The Table of the Value op Silver is calculated from the 
basis upon which the value of Silver is computed in the U. 
S. Mint and its branches, vjz: 

99 ounces of pure Silver is worth $128-00; or 

11 ounces of standard Silver (900 fine) is worth $12.80. 

Hence, 1 oz. of pure Silver is worth $1.29.29. 
1 oz. standard Silver is worth $1.16.36. 

Silver usually commands a Premium, which varies with 
the supply and demand.

PROPERTIES OF GOLD. 



Gold has been known from the earliest ages, and we find representations of Gold- 
washing and melting on Egyptian tombs dating back to 8.500 I!. C. 

The alchemists called it the king of metals and gave it die symbol of the sun. 
The Latin name for it ■ is Aurum from which its chemical symbol A 11. is abbreviated- 

It is the most ductile of metals, but the slightest admixture of other metals im- 
pairs its ductility. 

Its atomic Weight is 196, its mean specific gravity 19.33, it melts at 20.12° F. 
and in cooling contracts more than any other metal. In the oxyhydi me or 

the spark of a strong electric battery fine Gold wire can be volatilized. 

Gold is insoluble in Nitric-Sulphuric or Muriatic Acids, but Chlorine or mix- 
tures evolving Chlorine as well as Bromine dissolve it. Nitromuriatic Acid (Aqua 
Regia) is generally used for the purpose. 

It readily amalgamates with Quicksilver and alloys with most metals by fusion 
with them. 

From its solution Gold is precipitated by Sulphttreted Hydrogen as black 
Sulphide of Gold, which is insoluble in Nitric Acid, but soluble in Aqua Regia and 
in yellow Sulphide of Ammonium. 

Ammonia precipitates reddish yellow fulminating Gold (a very explosive 
Compound). 

Salts of Protoxide of Iron, Arsenious Acid, Protochloride of Antimony, Sul- 
phurous Acid, Oxalic Acid and many other organic compounds, precipitate metallic 
Gold as a reddish brown powder. 

Protochloride of Tin produces even in dilute solution of Gold a b autiful pur- 
ple coloration and prcipitate. 

Before the blowpipe Gold, if pure, fuses to a bright bead without incrustation. 
Gold is found in its native state alloyed with from 6 to 16 per cent, of Silver, in 
pyrites, aud in Tellurites. Traces of Gold are said to have been found in the 
water of the ocean.

NOTE TO GOLD TABLE, 



The following Gold Table containing the value per oz. is calculated from the basis that 
387 oz. aipure Gold (1000 fine) is worth $8000. Hence 1 oz. is worth $20. 671834625, and the 
loio of an oz. (decimally expressed as .001 fine) is worth $0.020671834625. I jQrtUi~. - If- 2-^ 

What we usually callfineness, therefore, is simply the •weight of fine metal contained 
in a given quantity of mixed metals or alloys. For instance in a Gold or Silver bar which 
is reported to be 850 fine, it is simply meant that in 1000 parts by weight, 850 are fine gold 
or fine silver, as the case may be. 

In our mints, the value of gold is computed from standard weight; that is, gold which 
is 900 fine, that being the fineness of our gold coin as required by law. The formula in this 
case is, 43 oz. of standard gold are worth $800. Hence, multiply standard oz. by 800, and 
divide by 43, and you obtain the value. 

Example: — Take 126," oz. at 856 fine, and we obtain the result thus: 

126.15 oz - 
856 fineness of gold.

To find value per oz., divide total value ($2,232.22) by standard oz. (119.982) and you 
have $i8.6o 16 which will be seen by reference to the table is the value of 1 oz. of gold at 
900 fine. 

The value in this case would have been ascertained thus: By reference to the Gold 
Table and opposite 856, the value of one oz. 856 fine is $17,69.51. Hence,

The foregoing table is computed from an assay of 20 grammes, which 
is a convenient amount for a crucible assay. When a scoritication assay is 
made, two scori tiers are used, with 10 grammes in each , and the two but- 
tons (which should weigh ex.ietly alike if the assay is correct) ate weighed 
together and treated as one assay. It is then only necessary to compare 
the tables with the number of Milligrammes obtained, in the first column; 
in the next will be found the number of ounces to the ton, and the value ot 
gold and silver in the other columns. A single example will fully illustrate 
it. 

20 grammes of ore yield a metallic button of gold and silver weighing 
830 Milligrammes. 

Boiled in Nitric Acid. — Gold weighing 32 Milligrammes remains. 

380—32 Gold=348 Silver. 

In the first column find 32 Milligrammes and yon hare 46.666 ozs. Troy 
and its value in gold column, 8964.68. 

In the first column find 348 Milligrammes. To do this you must add 48 
and 300, and you have 69.999 +437.499=507.49 ozs. Troy, and its value 
in silver column 90.50 4 565.54=$656.14. 

The result will be, 

Gold 46.666 ozs. Troy =$964.68. 

' Silver 507.49 " " = 656.14. 



Value per ton of 2,000 lbs $1,620.82.
